Memo to Self:

"I care so much for you that I would give you anything and ask for nothing"
is, ultimately, not going to prove anything nor impress anyone, much less sway them into reciprocating your love. It doesn't work on you, Self; why would you expect it to work when you pull it on anyone else?

Oh yeah: neither is it a healthy nor a sustainable position to put yourself in. But you knew that already.
